FC2 Online Web Service Open Redirect (Unvalidated Redirects and Forwards) Cyber Security Vulnerabilities

 

Domain:
fc2.com

“FC2 (founded July 20, 1999) is a popular Japanese blogging host, the third most popular video hosting service in Japan (after YouTube and Niconico), and a web hosting company headquartered in Las Vegas, Nevada. It is the sixth most popular website in Japan overall (as of January 2014). FC2 is an abbreviation of “Fantastic Kupi-Kupi (クピクピ)”. It is known to allow controversial adult content such as pornography and hate speech (unlike many of its competitors). The company uses rented office space for its headquarters which it shares with many other U.S.-based businesses. It also pays taxes in the United States. The physical servers are located in the United States. However, it is believed that the majority of the company and its users (including employees) are located within Japan” (Wikipedia)

 

The Alexa rank of fc2.com is 52 on February 18 2015. It is the toppest Japanese local website sevice.

 

 

 

(1) Vulnerability Description:

FC2 online web service has a computer cyber security bug problem. It can be exploited by Open Redirect (Unvalidated Redirects and Forwards) attacks. Here is the description of Open Redirect: “An open redirect is an application that takes a parameter and redirects a user to the parameter value without any validation. This vulnerability is used in phishing attacks to get users to visit malicious sites without realizing it.” One consequences of it is Phishing. (OWASP)

 

The program code flaw can be attacked without user login. Tests were performed on Microsoft IE (9 9.0.8112.16421) of Windows 7, Mozilla Firefox (37.0.2) & Google Chromium 42.0.2311 (64-bit) of Ubuntu (14.04.2),Apple Safari 6.1.6 of Mac OS X v10.9 Mavericks.

 

In fact, during the test, it is not hard to find URL Redirection bugs in FC2. Maybe fc2.com pays little attention to mitigate these Vulnerabilities. These bugs were found by using URFDS.

 

 

 

(2) Use one of webpages for the following tests. The webpage address is “http://securitypost.tumblr.com/“. Can suppose that this webpage is malicious.

 

 

Vulnerability Disclosure:
Those vulnerabilities were reported to Rakuten, they are still unpatched.

Google DoubleClicK System Bugs Could Be Used by Spammers

Google DoubleClick.net (Advertising) System URL Redirection Vulnerabilities Could Be Used by Spammers

 

Although Google does not include Open Redirect vulnerabilities in its bug bounty program, its preventive measures against Open Redirect attacks have been quite thorough and effective to date.

 

However, Google might have overlooked the security of its DoubleClick.net ​advertising system. After some test, it is found that most of the redirection URLs within DoubleClick.net are vulnerable to Open Redirect vulnerabilities. Many redirection are likely to be affected. This could allow a user to create a specially crafted URL, that if clicked, would redirect a victim from the intended legitimate web site to an arbitrary web site of the attacker’s choosing. Such attacks are useful as the crafted URL initially appear to be a web page of a trusted site. This could be leveraged to direct an unsuspecting user to a web page containing attacks that target client side software such as a web browser or document rendering programs.

 

These redirections can be easily used by spammers, too.

 

Some URLs belong to Googleads.g.Doubleclick.net are vulnerable to Open Redirect attacks, too. While Google prevents similar URL redirections other than Googleads.g.Doubleclick.net. Attackers can use URLs related to Google Account to make the attacks more powerful.

 

Moreover, these vulnerabilities can be used to attack other companies such as Google, eBay, The New York Times, Amazon, Godaddy, Yahoo, Netease, e.g. by bypassing their Open Redirect filters (Covert Redirect). These cyber security security bug problems have not been patched. Other similar web and computer attacks will be published in the near future.

Domain:
google.com

 

“Google is an American multinational technology company specializing in Internet-related services and products. These include online advertising technologies, search, cloud computing, and software. Most of its profits are derived from AdWords, an online advertising service that places advertising near the list of search results. Google was founded by Larry Page and Sergey Brin while they were Ph.D. students at Stanford University. Together they own about 14 percent of its shares but control 56 percent of the stockholder voting power through supervoting stock. They incorporated Google as a privately held company on September 4, 1998. An initial public offering followed on August 19, 2004. Its mission statement from the outset was “to organize the world’s information and make it universally accessible and useful,” and its unofficial slogan was “Don’t be evil”. In 2004, Google moved to its new headquarters in Mountain View, California, nicknamed the Googleplex. The corporation has been estimated to run more than one million servers in data centers around the world (as of 2007). It processes over one billion search requests and about 24 petabytes of user-generated data each day (as of 2009). In December 2013, Alexa listed google.com as the most visited website in the world. Numerous Google sites in other languages figure in the top one hundred, as do several other Google-owned sites such as YouTube and Blogger. Its market dominance has led to prominent media coverage, including criticism of the company over issues such as search neutrality, copyright, censorship, and privacy.” (Wikipedia)

“eBay Inc. (stylized as ebay) is an American multinational corporation and e-commerce company, providing consumer to consumer & business to consumer sales services via Internet. It is headquartered in San Jose, California, United States. eBay was founded by Pierre Omidyar in 1995, and became a notable success story of the dot-com bubble. Today, it is a multi-billion dollar business with operations localized in over thirty countries. The company manages eBay.com, an online auction and shopping website in which people and businesses buy and sell a broad variety of goods and services worldwide. In addition to its auction-style sales, the website has since expanded to include “Buy It Now” shopping; shopping by UPC, ISBN, or other kind of SKU (via Half.com); online classified advertisements (via Kijiji or eBay Classifieds); online event ticket trading (via StubHub); online money transfers (via PayPal) and other services.
